Hey guys, some advice about the wave boards please,
well in estonia we dont have those super radical waves, except Ristna in Hiiumaahttp://www.loodusemees.ee/aa/mi/000723aa010.jpg
so, some advice, should i get a 65l+ or a 76l board?
i have a freestyle board and my sail range will be 4.2-5.6 and il get a 3.7 and a 3,3 later

It depends a bit on your level and on exactly which boards you're looking at. But at that weight, no doubt a 65 liter board will be a more all round wave sailing board and when you're that light even most small wave boards will handle a 5.6 OK with the right fin.

But if you focus more on the less epic but more common days with maybe onshore and not so much wind and if you're not yet a super competent wave rider, than the bigger board could be the best choice. You will struggle a bit more with smaller sails, but that might be worth it.
